Abstract: A refrigerator includes a refrigerator body and an icemaker. An ice making chamber is defined in the refrigerator body. The icemaker is provided in the ice making chamber. The icemaker comprises a mold shell and a drive mechanism. The mold shell is provided with a water inlet and comprises a plurality of sub-mold shells. The plurality of sub-mold shells are configured to be switchable between a separated state and a closed state. The plurality of sub-mold shells are away from each other in the separated state, and the plurality of sub-mold shells are close to each other and closed in the closed state. The drive mechanism is configured to drive the plurality of sub-modules to switch between the separated state and the closed state.

Abstract: A refrigerator includes a refrigerator body and an ice maker. The ice maker includes a mold shell and a driving mechanism. The mold shell has at least one mold cavity and a water inlet. The mold shell includes a first sub-mold shell and a second sub-mold shell. One of the first sub-mold shell and the second sub-mold shell is fixed, and another of the first sub-mold shell and the second sub-mold shell is movable. The driving mechanism is configured to drive the first sub-mold shell or the second sub-mold shell to switch between a separated state and a dosed state. The second sub-mold shell includes a heating mechanism, a second shell portion, and a second mold portion. The second mold portion is disposed in the second shell portion, and the heating mechanism is disposed on a side of the second shell portion away from the second mold portion.

Abstract: A refrigerator includes an ice maker. The ice maker includes a mold shell, a driving mechanism, a first push rod, a second push rod, and a connecting rod assembly. One of the first sub-mold shell and the second sub-mold shell is fixed, and another one is movable. The driving mechanism is configured to drive the first sub-mold shell or the second sub-mold shell to switch between a separated state and a closed state. One of the first push rod and the second push rod is fixed, and another one is movable. The connecting rod assembly includes a connecting rod. An end of the connecting rod is connected to the movable one of the first sub-mold shell and the second sub-mold shell, and another end of the connecting rod is connected to the movable one of the first push rod and the second push rod.

Abstract: The invention relates to a composite shock absorber for a polycrystalline diamond compact bit, comprising a drilling tool body having a water inlet, an impact body having a water outlet and forming a shock absorption cavity, a disc spring group having an annular pressing sleeve, a cylindrical torsion bar spring which has an external thread and a spline, is connected to the drilling tool body through threads and extended into an impactor and connected thereto through the spline, and the annular pressing sleeve, wherein bit vibration impact force is transmitted therebetween through a torsion transmission joint, and a bearing group is arranged between the lower end surface of the annular pressing sleeve and an annular step of the impact body. The composite shock absorber can weaken damage of the slippage effect to polycrystalline diamond compact cutting teeth, absorb axial vibration from a drill stem and prolong the service life of the bit.

Abstract: The present invention discloses a refrigerator and relates to the technical field of refrigerators. The refrigerator is invented to settle problems, such as increased external space occupied by a refrigerator when its secondary door is opened, increased difficulty in fetching goods in the refrigerator, and heavy loss of cooling capacity resulted from the full opening of an opening. The inventive refrigerator comprises a main door; an opening is formed on a door body of the main door; a guide rail is provided at an edge of the opening, and a secondary door is fitted on the guide rail; and the secondary door is connected with a driving mechanism which can drive the secondary door to slide along the guide rail, and as the secondary door slides along the guide rail, the secondary door can enclose or open the opening. The refrigerator of the present invention is used for preserving and freezing foods.
